摘　　要：介绍一种箱型自升式平台破损后剩余稳性的计算方法。基于稳性计算软件GHS,选用箱型自升式平台对在360°不同方向下剩余稳性的特性进行计算,并对传统的在横倾过程中用固定转轴的计算方法进行衡准校核,以及对横倾过程中由于横倾引起的纵倾变化而重新寻找无纵倾只有横倾的转轴的计算方法进行衡准校核对比,此方法可用于实际计算中自升式平台破损后剩余稳性的分析。A calculation method of residual stability for damaged pontoon shaped self-elevating units was introduced. Base on hydrostatic stability software GHS, two kinds of method were used to find maximum allowable VCG under the residual stability criteria. One is using trim-fixed method with all axes to be considered, comparing to the one with free-twist method with axis con- sidered to be variable when calculating righting arm. The method can be used in self-elevating damage stability analysis.
